Description

FIELD OF THE INVENTION The invention relates to a construction set of paving stones according to the preamble of claim 1. \

BACKGROUND OF THE INVENTION

Building sets of paving stones of various sizes are known. From EP 0 185 361 B1, for example, a set of paving stones has been known which exhibits five different forms of blocks in mutually matched sizes for laying certain patterns. Due to their square or rectangular ground plan, these cobblestones, as well as the cobblestones according to German utility model GM 84 18 436, serve for laying surfaces in the so-called tread. As is evident from FIG. 2 of the utility model, the cubes are arranged offset from one another in rows lying side by side, the width of the cobblestone being partly maintained in the grid dimensions.

If curves are also intended to be laid by means of these cobblestones, so-called curved stones or gems are used for this purpose, as shown, for example, in German Utility Model DE GM 86 17 086 or in German DE-OS 33 22 090. of model 86 17 086

- using a seven-cornered central stone around which the first row of gemstones is laid. Instead of such a multi-legged stone, a normal square stone or rectangular stone is also used.

T

When laying larger circular shapes, from a certain radius, in addition to wedge stones, rectangular stones or square stones are used, but they form slits between them, which open radially outwards. These open space spaces between the stones are larger for stone shapes with straight side walls than for stone shapes with domed side walls. Stone shapes with domed or combined side walls can move closer together so that the gap between the stones is generally smaller when inclined on the radially inward edge.

The use of stone shapes with straight or flat side faces therefore has the disadvantage that the use of square or rectangular cross-sections in a circular configuration results in greatly opening slits between the stones. For example, this can be clearly seen in Figure 11 of EP 0 227 144 ·

However, the use of flat side surfaces has the advantage that when laying stones in straight treads, the side surfaces are so close to each other that the consistency of the stone shapes is guaranteed. Furthermore, in the case of flat lateral surfaces, the smallest slot can be set between the stones, evenly laid. Finally, stones with flat side surfaces can be transported more easily and stacked.

In order to guarantee a certain minimum distance between stones with straight side faces, it has been known to form side studs or ridges, as is known, for example, from EP 0 227 144, FIG.

These studs, however, have the disadvantage that, like the shapes of the stones with the combined side faces, they do not allow or only very badly allow them to be stacked, since the stones lie on each other in a point or straight line.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a construction set of paving stones which does not exhibit the above drawbacks and which creates a set of stones by means of which a circular representation as well as a representation in a joined tread are possible.

In doing so, the set of stones should consist of individual stones which can be stacked very well for transport. Furthermore, it is to be achieved that the slits between the stones are as small as possible when laying in curves or circular laying. Finally, the set of stones is to be complemented by stones that create an attractive appearance for the required technical requirements.

SUMMARY OF THE INVENTION

This object is achieved starting from a set of stones of the above-mentioned kind according to the invention by the features of claim 1. Further details of the invention are set forth in the other subclaims.

The invention has the advantage over known cobblestones or even cobblestone sets, that an attractive, optically nice-looking basic form of the individual cobblestones with curved, i.e. curved side surfaces, is formed.

- -4 · paving blocks behave like paving blocks with flat side surfaces during transport and laying. In spite of this, the advantages of the lateral arching are retained, i.e. the individual stones can be tilted relative to one another, as the arched lateral surfaces permit.

By means of these measures, in conjunction with the selection of certain stone sizes, circular surfaces can also be laid which guarantee a high degree of respective lateral support of the individual blocks. currencies with each other by the interface. This applies to both straight and curved laying patterns. Furthermore, the size of the stones and the shapes of the stones in the building set are so coordinated that a high degree of nice optical appearance is achieved, which is particularly true for the laying of crossings.

DETAILED DESCRIPTION OF THE INVENTION

The paving block construction set according to the present invention consists of the cuboid paving blocks shown in Figures 1a to 1e, as well as the three curved stones or circular stones shown in Figures 3a to 3c and 6 to 8.

Figures 2a to 2e show plan views of the stones 1 to 5 of Figures 1a to 1e; Figures 4a to 4c show plan views of the stones 6 to 8 of Figures 3a to 3c.

The building set of paving stones is arranged in the size of the basic grid with length a

12,5 cm. In the cross-section, a quadratic 1/1 stone with a side length a, shown in FIGS. 1a and 2a, serves as the base stone. 1b to 1e and 2b to 2e, respectively. 3 and 4 at least

6One side surface in dimension and grid. This ^ dimension is drawn in the respective figures.

The cuboid stones of Figs. 1 and 2 are shown in 1/4 unit dimensions. The stone according to Figs. 1b and 2b is consequently a 3/4 stone with a lateral length b = 3/4 a. The paving block 2 shown in Fig. 1c, 2c is a 1/2 stone with a lateral length = 1/2 a. 4 or 4d in Fig. 1d and 2d is a 5/4 stone with a lateral length d = 5/4 a. The paving block něná shown in Fig. 1e, 2e is a 1 1/2 stone with a lateral length e = 6/4;

The annular stone 6 shown in Figs. 3a, 4a is formed as a 90 ° stone, with a lateral length and also clamped at an angle dLSi of 90 °. The circular stone 7 shown in FIGS. 3b, 4b also has a lateral length and a closed angle β of 30 °. The circular stone 8 shown in Figs. 3c, 4c has a lateral length α as well as a clamped angle 15 15 °.

The building block set with cuboid paving stones 1 to 6 as well as the round stones 6 to 8 exhibits the basic shape of the paving stones, which have crowned or arched side walls 6 as shown in FIGS. 2a to 2e or 4a to 4c in plan view.

Such collapsed side walls are known, for example, from utility model GM 86 10 102, FIG. 5.

This known form of stones is also shown in FIG.

5b of the present invention as a top view of the stone shape, as opposed to the known shape of FIG. 5c with flat side surfaces.

2. are formed as rounded edges.

The above-described stone shape provides a cobblestone, which is shown in principle in FIG.

5b · When such known stones are placed side by side on the stop, they touch along a perpendicular line which in plan view in Fig. 5b appears as a point 13 in the cross-section of the line of symmetry 14. Therefore, when laying these stones, The symmetry lines 14 often do not lie in a single line but form an obtuse angle. The symmetry axes 14.15 are not parallel to each other, as indicated in Figure 5b.

If the known cobblestone of FIG. 5e with the flat sidewalls 16 is laid in a straight tread bond, the sidewalls generally lie flat with each other unless they are laid on the gap or with a joint. Especially in transport, such stones provide advantages in transport.

If, even in the case of a paving stone with curved side walls 2 of the cobblestones 1 to 8, a flat stop surface is obtained on the side wall, the cobblestones according to the invention exhibit polygonal contact surfaces or contact surfaces on their side walls. These polygonal surfaces 17, for all the side walls to be collected, consist, for kagens 1 to 5, of an axially parallel contact surface 18, of length f, and of wedge surfaces 19 with lengths g, which adhere thereto on both sides of the connections. The total length of the polygonal surface 17, consisting of sub-regions 18, 19, is indicated

h.

The total length h of the polygonal surface 17 depends on the length of the side wall to be pumped. It extends almost or at least up to about 75 existing width of the side wall to be pumped.

2. The hardened area and to the right of the wedge surfaces 19 extend over the side wall panel 20 and the wall region has a length i. This remaining length 20 of the respective side wall a to e serves for better drainage of paving blocks laid against the surfaces 18.

. The contact surfaces 19 parallel to the symmetry axes 14.15 therefore serve as flat lateral contact surfaces between individual cobblestones, the width f of this contact surface being about 1/3 of the respective side wall. wall sections 20. Thereby a very flat contact between the stones is achieved both during laying and also

-9When transporting stones.

The depth or thickness s with which the wall section 18 protrudes over the accumulated wall% laterally in the region of the symmetry axes 14.15 has the specified dimensions s ^ 1.5 mm. Due to the gathering of the lateral surface 2, the polygon surface extends over the wedge-shaped fold with the surface portions 19 to a width s 2,5 2.5 mm. However, the polygon surface 17, consisting of the surface sections 18.19, may extend as parallel as possible to the side wall 2 to be collected, but with straight surface sections 1a, 19 being present.

The paving stones according to FIGS. 1 and 2, as a rule, have on their crowned side walls 2 rising surfaces 1 / polygon, consisting of 18,19-surface areas. By way of example, the corresponding dimension is drawn in a single stone shape.

The height k of all polygon surfaces 17 also extends over at least 75 uniform overall heights m of all cobblestones. The residual dimension n pointing upwards, with the surface section, serves to cover the seated surface 17 of the polygon in the laid condition, so that the cobblestones, seen from above, have essentially only the appearance of the collapsed side surfaces 2.

Above the surface 18 there is a further, symmetrically arranged, aligned surface 31 in the surface section, but whose width is only about 1/3 of the width g of the contact surface.

The surface 18 also has the task of creating a natural spacing between the stones and thereby creating a natural joint. Such means for forming a joint as a bearing surface are known per se from EP 0 227 144. However, they extend either over the entire lateral surface or are formed only by individual rounded studs.

The curved or circular stones 2 to 4 according to FIGS. 3a to 3c and 4a to 4c do not differ in the construction principle in respect of the crowned side walls 60 of suitably fitted polygon surfaces 17, consisting of contact surfaces 18 as well as wedge surfaces 19 from the rectangular blocks described above. paving stones 1 to

2. The same applies to the other construction of the curved stones £ to £ 3 with a flat top surface 10, a rounded transition surface 11 and rounded perpendicular edges 12. The accumulated lateral surfaces £ in dimension and base grid exhibit essentially shaping as © 1/1 paving 1a or 2a. Reference is made here to the corresponding description of the side walls.

The formation of the polygon surface 17 with the flat side surface 18 and the wedge surfaces 19 is particularly suited for the production of the arrangement of the hinges for the circular or arched laying of the cobblestones. For this purpose reference is made to Figures 3 to 7.

As mentioned in the introduction of the description, paving blocks with a rectangular and square cross-section p are often used for laying curved patterns for laying. As shown in EP

10 and 11, as well as the corresponding representation in FIG. 5c of the present invention, a relatively large opening angle occurs with a paving block with straight side walls 16 even with a small tilting of the cross axis 14.15 of symmetry. touch on the joint line, the ground plan of which is shown in paragraph 21. Notwithstanding the fact that this gives the laid surface a less suitable appearance, a large intermediate space 22 is formed on the opposite side, which may in part greatly affect the feasibility of the surface. The linear contact surface 21 can also lead to damage to the stone, especially in the area of the edges. Such cobblestones with straight side walls 16 are therefore very poorly suited for incorporation into a curve pattern. This is also evident from Fig. 11A ^: P 0 227 144.

If a mold of stone with a collapsed, i.e. rounded side wall as shown in FIG. 5b is chosen, the upper opening angle due to the arched side wall is already made larger than the one shown in FIG. Here, too, there is a direct contact of the stones at point 13 ^z , ie in the off-center position. If the symmetry axes 14.15 of the two stones fold further apart, the upper angle increases even further, while lowering the lower angle ·

The effective passable upper surface 10 is also determined by the curvature dimension of the transition surface 11. Thus, the shape of the stone in Fig. 5c with the straight side walls 16 in the corner regions shows a greater break A + B of the upper deck surface by creating a larger

In Fig. 5b, the interruption A + B + C of the platform surface is dimensioned to absolutely small values. This is done by creating a smaller phase of the transition surface 11.

Fig. 5a shows the arrangement of the cobblestones of the present invention in the tilted position, that is, the symmetry axes 15 and 15 form an angle with each other. Due to the additional surface 17 of the polygon, the two stones 23, 24 are also abutted even at the angular position in the region 19. If the wedge surface 19 itself is again divided into polygonal sections, tilted stones can be formed without further different angular settings, with still flat sewage surfaces between the respective stones. The interruption A + B + C of the step surface 10 decreases due to this surface arrangement This means that the gap between the stones can be kept very small. The same applies to the opening angle.

With pitching of the invention can therefore be achieved within a wide range even in case of curve laying flat engagement or contact surfaces between cobblestones sebou.Při that preserves optically advantageous arched side wall 2 ⁱⁿ shape.

FIGS. 6 and 7 show the arrangement of the various cobblestones in a circular laying and are further explained. 7 represents, in principle, the quadrant of FIG. 6.

-13For creating a quadrant as shown \

In FIG. 6, with the building set of paving stones according to the invention, at first eight different rows are formed, which are shown in a circle in FIG. 6 and denoted by 1 to 8. Since the quadrant covers a 90 [deg.] Angle, the 90 [deg.] Stone according to the invention is first arranged as a center stone with a row of 0. Therefore, not only a normal square stone is used as the center stone, but an appropriately adapted 90 ^° stone.

All subsequent rows of circles 1 to 7 up to a circle diameter of about 2.0 m are formed by not equal to the number of N individual stones. This provides an excellent optical impression.

Thus, in the first row 1 * (first circular segment) there are three inner circular stones 7 with an opening angle β / ° 30 ° as shown in Figs. 3b, 4b. The use of the three inner circular stones 8 overlaps an arc angle of about 9θ

In the following row 2, the outermost circular stones 8 are used which have an opening angle. Optimization of this stone provides an angle λ * = 15.25 ^G opening.

The stones are arranged offset from row 1 so that the joints of the respective inner circle overlap at least in part.

The next row 3 is formed by the seven outer circular stones 8. The next row 4 ”is formed by the five outer circular stones 8 as

In the 5 ^M row there are six outer round stones 8 as well as five 3/4 stones 2. In the following circle 6 there are seven outer round stones 8 as well as six 3/4 stones 2.

In the next circle or the next row "1" there are no round stones or curved stones, but only fifteen 3/4 stones arranged side by side. Up to row 7, the sum N of the number of stones in each row is an odd number © (see column N in Fig. 6). Starting with the following row 8, thirteen normal stones, i.e. 1/1 of the stones 1 as shown in Fig. 1a, 2a are arranged. All successive rows may be built with this stone as well as in combination with other stones from the building set .

All rows of stones have side lengths and as a basic grid size, as shown in Fig. 6, rows 2, ”4 and” 5 are so offset from each other that on one side they extend over an angle of 90 °, which in one complete 7.

The representation of the circle according to FIG. 7 consists essentially of four quarters of FIG. 6.

in Figures 6 and 7, therefore, the 90th stone 6, both circular or curved stones 7 and 8 as well as 3/4 stone 2 and 1/1 stone 1 are applicable. Other stones of the building block set, namely 1/2 stone 2 as well as 5/4 stone 4 and 1 1/2 stone 2 are mainly used for laying surfaces in a continuous tread.

According to the present invention, the advantages of the known cobblestone with collapsed side walls are further developed in the sense that it is possible to precisely lay different stone shapes, always being there;

one contact surface instead of the contact seam in a straight line;

ce. For this purpose, at least the retained basic shape of the side walls with the fitted surfaces / many angles, which form the bearing surfaces during the fall of the contact surface and at the same time a spacer for the formation of joints, serves at least. In this case, the polygon surface extends over a large part of the respective side wall and thus forms side contact surfaces.

As can be seen from FIGS. 3a to 3c and FIGS. 4a to 4c, the circular stones or curved stones 7 to 8 also have arcuate stones on their outside (circular stone 6) and on their inwardly located (circular stone 7, 8): 32: 3 to 36 further sections 25 to 29 that rise similar to the polygonal areas 17 of the cuboid cobblestones from the domed side walls. In doing so, these sections 25 to 29 form flat surfaces which are formed in accordance with the contact surface 18. At 90 ° of stone 6, three symmetrically arranged surface sections 25 are arranged above the angle of 90 ^G , which now form a straight contact surface 16 Γ The angle area of these contact surfaces is now about = 20 °.

^The annular stone 1 also has two surface sections 26 arranged on the outer arc 33 with a flat contact surface 18 ^z . The angle area corresponds to ₂ = 10 °. ·

The section 27 of the areas of annular stone 5 abutting the inner annular arc 30 overlaps an angle region = 20 °. The fitted surface section 27 also has a contact surface 18 'as flat as possible.

The circular stone 8, shown in FIGS. 3c, 4c, with an open angle θ *, has on its outer arcuate surface 33 a surface section 28 which is constructed similar to the polygonal surface 17 of a cuboid stone. Therefore, ^the G? Official contact surfaces 18 and two wedge surfaces 19'nasazené at them from the side, which extend over the entire arc g3. As can be seen from the plan view of the circular stone 8 in FIG. 4c, the central, flat contact surface 18 'extends over a large angle area 4 = 1/3. Both wedge surfaces 19 '.

connecting the hay laterally, they are designed as flat as possible the connecting surfaces.

Inside the arc region 36 of the circular stone 8 there is a surface section 29 which, as a straight contact surface 18 ', extends as much as possible over the entire arc region.

The surface sections 23 to 29 also serve as flat contact surfaces as well as spacers for laying the cobblestones according to the invention. The same applies to the transport of these cobblestones, which easily bundle with their flat contact surfaces
